Similar to the wet willy, it's when you wet your finger with vaginal juice and give her a wet willy/swilly. Short for snatch willy.
I was fingering Patty on the balcony outside the party when I realized that the entire crew was watching us. I decided to give them a show and provide her with a nice wet swilly.
